The iStick Power comes with an ultra-large battery capacity of 5000mAh in a compact design, which can last you for a remarkably long time at any power setting. A beautiful, clear screen shows all your vaping information at a glance and the large, responsive buttons make the iPower a pleasure to use. Five output modes allow for versatility with a range of tanks and drippers. Alongside the standard wattage and temperature modes there is also smart mode and bypass mode which allows your iPower to behave as a mechanical mod would. Smart mode remembers your wattage settings for up to 10 wire resistances, great for if you are frequently changing between tanks and coils as it will automatically set your wattage to your preferred setting for your chosen resistance. Upgradeable firmware will ensure your iPower battery mod is always up to date, while stainless steel threads and a spring loaded firing pin means no need for adjustments when using various RTA's or RDA's. Dual circuit protection keeps you vaping safe and helps prevent over charging and over discharging.
